SURGICAL IMPLEMENT.

Specification of Letters Patent.

Patented Oct. 9, 1906.

To all whom it may concern:

Be it known that I, ALFRED LITTAUER, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Surgical Implements, of which the following is a specification.

My invention relates to a device for facilitating the instillation of medicaments into the uterine cavity.

For the instillation of medicaments into the uterine cavity a suitable syringe is employed having the point formed usually of gold or silver to render it non-corrodible by This point must be sufficiently large to adapt it to be introduced without injury to the patient, and this fact renders the point, because composed of a precious metal, very expensive. Moreover, the operation necessarily brings into contact with the os uteri the hard substance composing the point, which is objectionable, and it is difficult in the use of the syringe as hitherto practiced to prevent the entry of airbubbles into the uterine cavity with consequent well-known injurious results.

The object of my invention is to avoid the foregoing objections attending the instillating operation referred to by enabling it to be performed without requiring the hard substance of the syringe-point to be brought into contact with the os uteri and incidentally to enable the point to be much thinner than is now customary, thereby saving materially in the cost of the implement, and by enabling it to be performed without danger of introducing air into the uterine cavity and in a manner that shall cause the medicaments to be retained against overflow in the cavity until sufficient thereof has been absorbed into the body of the patient.

A further object of my invention is to provide for guiding the syringe-point to the opening into which it is to be inserted and for guiding my improved implement into its position of use.

To this end my invention consists in the construction of the implement of soft or flexible rubber, comprising a nipple adapted to be introduced into the uterine opening and provided with a longitudinal passage, which is preferably self-closing, and with a flange for guiding the implement in introducing it into its position of use and for guiding the,-

syringe-point to the nipple-passage.

Referring to the accompanying drawings, Figure 1 is a view in perspective of my implement. Fig. 2 is a view of the same in vertical sectional elevation. Fig. 8 is a section taken at the line 3 3 on Fig. 2 and viewed in the direction of the arrow, and Fig. 4 a view in perspective of an insertion-tool suitable for use in connection With the implement illustrated in the preceding figures for introducing it into operative position.

5 denotes the entire implement, which is preferably molded out of soft rubber or any other suitable material and comprises a nipple 6, rounded at its outer end and terminating at its opposite end in a flange, preferably in the form of a cup 7, affording a seatingsurface and guides for the purposes hereinafter explained. The nipple 6 is provided with a longitudinal slit 8, extending centrally throughout its length and affording a selfclosing passage by reason of the elasticity of the material. The slit may be formed by piercing the stem longitudinally with a suitable tool, (not shown,) such as a spear-pointed double-edged blade.

9 is an insertion-tool which forms no part of my invention, but which affords suitable means for facilitating the insertion of the director 5 into the proper position for use, and it comprises a slender rod 10, provided on one end with a handle 11 and near its opposite end with a button or stop 12. Preparatory to introducing the implement 5 into position for use the outer end of the tool 9 is inserted into the slit 8 through its opening in the cup 7, and the implement is then positioned in place by inserting the stem 6 through the opening leading into the uterine cavity, the cup serving to guide the insertion along the walls of the vagina. The tool 9 is then withdrawn and the syringe instillation-point inserted through the slit 8, the concave surface of the cup 7 affording a guide for the end of the syringe-point to the inner end of the passage 8. The contents of the syringe are then discharged into the cavity, whereupon the syringe may be withdrawn. Upon Withdrawal of the syringe-point the slit immediately closes, thereby preventing the escape of the medicament from the cavity wherein it may be retained until absorbed or as long as desired, the release of the medicament or of sertion-passage, and a flange on one end of the superfluous portion thereof being effected said nipple, for the purpose set forth. 15

A surgical implement of the character The provision of a self-closing passage in described, composed of soft rubber and com- 5 the stem in addition to the function thereof prising a nipple terminating in a cup-shaped just described serves to prevent air-bubbles flange and provided with a longitudinal selffrom being forced into the cavity when the closing syringe-point insertion-passage, for 20 syringe-ploirlit is inserted. d the purpose set forth.

What 0 aim as new, and esire to secure [0 by Letters Patent, is ALFRED LITTAUER' 1. A surgical implement of the character In presence of described, comprising a nipple provided with L. HEIsLAR, a longitudinal self-closing syringe-point in- J. H. LANDES.
